About us

Our vision is to provide integrity in the industry through the application of a passion for the science of diamonds, unrivalled diamond expertise and market-leading innovative technology. As a result, our mission is to grow and strengthen consumer confidence across the diamond industry.
 

Our History

De Beers Group, the world's leading diamond company, established the International Institute of Diamond Grading & Research (IIDGR) in 2008 to provide a premium grading service to the market supported by innovative technology.

With an initial investment of US$10 million, a new facility was established in Surat, India in 2015 with the capacity to process over US$500 million of diamonds every year.

Since then IIDGR has continued its drive for integrity in polished diamonds by developing market leading synthetic testing services and detection instruments. To support this demand, a further US$5 million expansion was completed at the Surat facility in 2016.

2017 saw the launch of our education programmes which draw on the unparalleled expertise within De Beers Group.

In 2019, IIDGR was rebranded to De Beers Group Industry Services to align more closely with the rest of the group.

In 2020, De Beers Group Industry Services was re-branded De Beers Institute of Diamonds, highlighting its expertise for the benefit of both the trade and consumers.

In 2021, The De Beers Code of Origin, a trusted source programme that reflects De Beers’ deep commitment to social and environmental responsibility, was launched. The De Beers Code of Origin is reflected in the unique inscription on the diamond discovered by De Beers in Botswana, Canada, Namibia or South Africa
